I think MM's idea is a good one from the consumer standpoint - but not profitable from the business standpoint simply because point.com isn't making much so a competitor splitting the market isn't going to do well profit wise.

I don't think point.com could have a high profit margin based the airlines lack of willingness to may much $$ out for their miles. If someone shows I am wrong on this, then giving points.com competition would be a great business idea.
