When someone uses the flash client, the connection still originates
from his machine, no matter where the client is hosted (Flash runs on the user machine, not the server that hosts the files). There would be
no policing needed and it would make things very easy for those who
want to check out the mud fast (and that is the majority of young ppl today who are blasted with information on the net all the time).

Even if the flash client, one-click and you are playing CF thing is not
possible, having a single .exe or .zip (like ytin with scripts for CF) that the user can download, double-click to run and be immediatelly playing CF would go a long way towards attracting users who are not experienced mud players. If you have a look at the IRE forums, you will find *many* of those. I don't think IRE would go to the trouble of creating first, their own custom java client and then hiring that guy
to fully work on the flash one. They saw return-on-investment.
