What do you mean?
I can mind 3 servers, which you could mean.
1. HDL-Dump-Server (the original app and all other servers are based on this one)
2. OPLs integrated HDL-Dump-Server (based on the first server)
3. HDAdvance 3.0s server (I never worked with it, but I assume it is either HDL-Dump, or PS2-Link and still both are based on Homebrew then... I guess, it is the HDL-Dump-Server...)
So equally which server you choose:
-all should be compatible to each other
-all PC-Apps (all those various dump-GUIs and whatsoever is written for HDL-Dump) should be compatible to each of those servers
