Yeah, the direct link downloads in the browser for me too.
Make sure your friend doesn't have mod downloads from locators turned off in his launcher settings.
Launcher -> Configure -> Advanced -> PeerToPeer tab -> Advanced -> Download from locators (Direct download URL) -> make sure "Map mods" is checked.

I'm not sure what to say then.
It should work!
You could always send the mod to your friends and have them put it in the same folder you have it in. Then when they load the map (or any other map that uses that mod) online it will display properly, since they already have the mod.
Maybe someone else has an idea...
By the way, 20MB isn't that big for a TM2 texture mod. I've seen some over 100MBs.
