Good call as this is a FAQ. Recorded now:

2G is what INEX run, yes.

Recommended really depends on your size (or, more specifically, the 
amount of memory required to generate your route server configuration. 
The code is memory inefficient here and we have internal tickets to fix 
that.

You'd probably be fine with 512M for a small IX but for large route 
server configs with lots of member prefixes, >=2G is required.

4G

It's not an issue in practice (shared mem for a lot of things) - the 
issue is route server conf generation as above.
