I asked this: Is a 'telecommuter' SLA a good idea? Does it even exist?
I don't know where else on StackExchange to ask other than SuperUser. This clearly falls under the general SuperUser description of "Q&A for computer enthusiasts and power users" and in the faq with "personal and home computer networking".
I edited the original question so that I can get educated about SLAs as they apply to telecommuting rather than asking for specific ISPs.
I got some good answers to this question too!
