Its nothing to do with how the server is implemented. It is about
finding a vendor who is prepared to sell single runtime licenses. Last
time I checked, the smallest number you could purchase was a bundle of
10 runtime licenses and this came out at a bit more than the cost of
the SDK. 

There has been reports of some sites who have said they are going to
sell single licenses, but last time I checked this was still a plan
and not actually available. 

this issue has been raised a number of times on the list. If you have
details of where you can purchase a single runtime license, it would
be great if you can post the details so that others can take
advantage of it and the details can go into the list archive.

Personally, I don't think $300US is too much to pay for a good quality
stable software TTS for Linux - but then again, I was lucky in that my
employer purchased mine in return for some proof of concept web based
speech demos.

regards,

Tim

There are two types of people in IT - those who do not manage what they 
understand and those who do not understand what they manage.
