Sounds good to me, Amos. The issue is with an HA solution though is that it often costs an awful lot of money to build. If it works well the theory is, as you say, the client then pays the full cost. However, it is often the case that the POC will do the job that you say it will and no further deveopments costs are required! What if the client decides not to fund it? For a small company (Like ours!) that could be disastrous. Even if they do agree it works, there has been an 'up front' cost that would seriously affect cash flow:-(

What I mean is how does a small company justify building the clients HA system without knowing if they are going to be paid or not? Would one of the 'big boys', like HP in our case, subsidise the development costs on the premise that they will get paid eventualy? I don't think that they would. Perhaps part of my POC presentation should be how to get funding in the first place? Hmmm.

Thanks for the input anyway. It is very much appreciated. Any thoughts at all, technical or not, may well help!

Cheers
