Max Map Size for Bnet?

Max Map Size for Bnet?

I was browsing through the models section and saw a post saying that there was a 4 meg cap on maps for bnet. I never thought about that, but i am curious now,what is the largest file size allowable for a map to be hosted on bnet?

4 Megs.

Same on LAN. Kinda sux if you have a map that you wanna play on LAN and don care about load time.
