VS is not part of Skyteam, thus there's no such thing as Skyteam benefits for access to the Clubhouse. The JV is what allows DL elites to get access. Thus unless you're flying J on VS/DL flights that are operated out of T3 you don't get Clubhouse access.

Interview with Michael Wisbrun of SkyTeam
 

Interesting interview with Michael Wisbrun, Managing Director of SkyTeam: AirwaysNews High Flyer Interview: Michael Wisbrun of SkyTeam

Key points:

• New SkyTeam lounges in Beijing, Hong Kong and Dubai planned for 2015 (as discussed in this thread: 3 new skyteam lounges planned for 2015)
• Recognition of two 'holes' in the SkyTeam network: Brazil and India*. Gol's partnerships with DL, AF/KL, etc are seen as partly addressing Brazil; 'no solution yet' for India.
• Mention of the 'SkyTeam transfer programme', that is trying to improve transfers between different SkyTeam airlines. In particular, this includes a 'major IT project' to ensure 'that any employee at an airport can change the itinerary in the system of our member airlines', to be achieved this year. (Given the importance of service recovery in the event of IRROPs, this sounds like a useful development - although it's also surprising that apparently no alliance has managed it so far! The 'SkyTransfer programme' has been mentioned earlier in this thread, but I have seen very little published information about it. It seems it is more of a behind-the-scenes initiative than, say, SkyPriority - but it would still be interesting to hear more details...)
• Plans for a 'multi-airline booking tool' that would apparently facilitate award redemptions on different SkyTeam carriers. (Again, this sounds like a useful improvement - given that, for example, FB currently allows online booking of rewards on only some, but not all, SkyTeam airlines).

* Wisbrun also suggests that KQ is covering Africa adequately - and although I like KQ, personally I would like to see another SkyTeam carrier somewhere in West Africa. *A has SA, ET, MS and soon AT - so another SkyTeam carrier in Africa would not seem unreasonable, if they could find the right partner...

This article (Skyteam to launch alliance-wide online booking tool) has more on the last two bullet points above:

• An alliance-wide award booking tool means that 'by the end of this year', every SkyTeam FFP will have an online tool that enables award booking on other SkyTeam members, rather than having to phone a call-centre. Apparently, the tool is already in place for ten members (the article doesn't state which ten...)
• It also mentions SkyTransfer, allowing any member airline to access a passenger's PNR and make rebooking in the event of IRROPs.

both are positive moves - shame they aren't already available

SkyTeam Awarded Airline Alliance of the Year by Air Transport News
 

The press release includes a fairly standard list of recent achievements, such as the rollout of SkyPriority, new lounge in SYD, implementation of SkyTransfer, and the alliance-wide online booking tool for award tickets mentioned above.
