Yea there isnt any MC Beta servers made by our comunity members since your comp needs to have at least 4gb ram and pretty fast internet. But you can check out other public servers here

Rokoshu konws one Beta server in witch he builds with his friend (At least thats what he said in SB) Dont know if he will give you IP
As for myself i cant play beta survival since my wireless internet is too slow(It basicly sucks).
Hopefully i will get 3G internet this summer.
I Also recomend you to first play singleplayer a bit. You will get confused realy fast in multiplayer if you wount understand singleplayer. (At least thats what hapened to me).
Remeber almost all multiplayer servers dont allow you to use hacking programs like INVedit etc
If you havent been in this site then i recomend you to wisit it too minecraftwiki.net
Happy Crafting.
Some guy that does DTS shapes and levels.
