Hopefully the price tag will be well within the price range of anybody looking for a basic hosting package, but it would be targetted at multiplayer flash developers.
150MB can be difficult to fill unless you have a massive database or are putting lots of files up for download.
2000 ports is excessive, but there are plenty go go round. I might impose a lower limit than this, in case there is enough interest to warrant a larger server. The total number of ports won't change, and 64 or 128 ports should still be more than most people will require, but this is negotiable.
I might take this question to a flash specific forum - I may have read somewhere that somebody was looking for a low price hosting package, but found the prices at the time to be too high.
[edit]
The above is based on sharing the
Xilo XV1 service amongst 32 people.
However, I just found the
SWVPS LVPS-1 service, which has double the storage space and monthly bandwidth of the above for a little bit less than the Xilo package.
I'll check the customer feedbacks and reviews before making a descision.
