A 128MB VPS can comfortably support an obfsproxy bridge - just get a
provider that doesn't reboot you a ton.  I've run a number of such
bridges.

I would not go below 512MB RAM for a relay that is going to handle
more than 2Mbps (about 200KB/sec) - you will eventually run out of RAM
and Tor will be killed, and that's not great for the network.

My source for the above is a lot of blood, sweat and tears with Tor on
the Raspberry Pi model B.  :)
