Ask Autodesk officially. Sure they are certifying some of their products on Citrix - but they sure as shit don't expect you to draft on them. Ever. Things may change going forward - but as long as Autodesk is writing the software, don't hold your breathe. Hey! it rings true for most of Metro-CBD's. Looked into this with Vertel. They are going to get back to me when they can get the initial install cost under $130k. Even then, monthly figures are at LEAST $1500/month. Well no. I don't think you're going to get Riverbeds on the cheap - ever. Riverbed's potential customers grow smaller and smaller every year with increase bandwidth and reduced latency and then the advent of the cloud renders most of it unnecessary. I think you're going to find that things like on-premise SBS Essentials - or whatever they are going to call it now - that blend with hosted solutions in terms of management. Maybe MS will do server-side local caching - but i really don't see it - Its a temporary problem thats likely to be resolved in < 10 years, possibly 5. No company is going to invest in the software development, marketing and support to make that happen for such a tightass market. By the time i implement something with hotswap drives and a decent warranty - i'm about 3x that price. The $40/month option seems better imo - You end up with a Office ProPlus subscription as well - if your customer doesn't need Access/Publisher, its not super great (over say $250 Home and Business) - but if they do, it starts to look appealing. Particularly for Terminal Server users ($1000+/copy). A NAS for that is roughly $600. And you're right - for all the problems of Windows, most SMB based NAS's have more. 1 word - Leasing.
