Hi, 
 
I am looking for a variety of information on MTM(Mark to Market)
applications available for sale in the banking and finance industry,
both domestically (UK) and abroad.
 
Specifically: 
 
1.  How big is the industry by # of companies and total revenues? 
2.  How do prices compare? 
3.  Who are the biggest players? 
 
Sources for any data are appreciated and I would also be interested in
just a couple really useful sites for this kind of info...
