Based on Jason's recommendation and my near constant issues with "CPU Throttling" on Bluehost I have created a Media Temple "GS" or Grid Service account.
I use S2Member to run online conferences that run over a 6 month or so time period. And at any give time I may have 4-6 conferences running. Shared hosting doesn't work to well with all those S2Member installations running.
I suppose at some point I could run all my conferences of off one S2Member installation....
I will keep you posted on how it works.
