Although I like many pieces of the Encina product (especially functional design -- See Encina Product Overview, Monitor System Admin Guide & REf, etc.) there are a few issues that concern me.

1. DCE requirement -- if you think that XA locks the product out of sites, try looking at the system's dependence on DCE services. They do provide some great resources to take advantage of, but not that many vendors offer DCE services. Those that do usually do it in a seperately priced package (from OS or machine). Until DCE becomes more widely accepted and offered, this reliance may be a liability for Encina.
2. How many layers can you go through?? -- Looking at the Product Overview, I count no less than 4 software layers between the application and the OS (5 if you want an SNA gateway). How badly will this knock performance?

Please don't get me wrong, I think Encina has great potential. It will just take some time and commitment before it becomes a cost-effective alternative.
