We use several LMI services on our tech services side, but LMI Central may be over-kill unless you are changing configurations much.
I agree with Wendell that Ignition combined with LMI Free is *very* effective. Fast, single app to click on easy. Your staff will appreciate the ease-of-use.
Buying three copies of Ignition and being done with it will be far faster with less moving pieces than implementing SBS or another server that you then need to maintain.
That said, then things that you then focus on is the Internet providers and the network performance. When I read DSL, I wince from years of iffy client experiences. I am thinking I need to do a Physician-friendly blog post on measuring network performance so that you can anticipate what the performance is going to look like.
One of the things that practices do (which we recommend) that use our managed servers is having a back-up plan for if your Internet provider goes down. With 4G/LTE phones, WIMAX, fixed wireless, you have options.
