Ac's simple SaaSy version of itself I suspect will be attractive to end users who want functionality without infrastucture headaches... those with multiple sites...and those burdened with excessive overhead.

I didnt consider a SAAS solution 3 years ago because i was limited locally to a subpar DSL connection. Today I would certainly try AC in the cloud. My landlord finally upgraded (when HE decided to try Practice Fusion) I now have ridiculous speeds up and down (yup AC tech support called it "ridiculously fast"....yeah we bad...) I use a cloud scheduling software and changed my phones from landline to IP. In 6 months only twice have I come in and oh *&%$ ... no internet connection. My niece smuggly pulled out her iphone and scheduled several patients via 3G, all IP phones were previously set to forward to my cell if no connection. In both cases, internet connection was restored within an hour. My lesson, have a backup plan... a devise suitable to for data input with mobile broadband or wifi can easily keep you going until the more secure connection is re established.

SaaS is liberating. When it works. And fortunately the internet pipelines are getting faster and more reliable. While comparing my landlord's MU wizard on P.Fusion - i found the experience not at all unsettling - hated the pop up ads .. side note - you eventually get over it just like with google or facebook or practically every "free" service on the internet ... you learn to filter the ads so long as they are not too offensive or garish. My loyalties remain with AC but if offering SaaS proves too costly to recoup ... just consider.

Liberating technologies help small businesses. Imagine having off site schedulers ... to extend hours available for pt to schedule and free up day time staff for other tasks - off site document management - all your updox faxes neatly tucked into the chart with flags waiting for you at the beginning of the day - night call or holiday coverage leaving messages attached to patient records - centralized backoffice services for AC users is a simple set up for groups in the cloud.

If security, data ownership, performance and price are "Amazing" I would give it a try.
