Brian Madden posted an entry wondering about the future of VDI vendors who only do one thing well here. The following is my response (also posted on his site):

I think point solutions, or “one-hit wonders” are doomed.

As you point out, they are difficult to integrate into other offerings and, even if they could be integrated, the aggregate price would be astronomical.

More complete solutions, like VERDE from IBM and Virtual Bridges, offer the best hope for delivering full-featured value at an economical price… and, without the wait.

Consider that VERDE is shipping today and includes almost everything on your list of required features for successful adoption (and more): distributed connection broker, efficient hypervisor, multimedia display protocol, single Gold Master image management, personalized sessions (docs and settings), clustering, dynamic provisioning, integrated client-side hypervisor for mobile users, ability to automatically replicate gold images to branch servers/sites for overcoming any latency issues, no bit duplication at all… and all this for a paid up license of $50 per seat (in volumes of 1000 or more).

Solutions like this will begin to shine more brightly as more users emerge from their economic bunkers and begin to actually deploy VDI and see demonstrable benefits. This will separate the vendors with products that are integrated, easy to use and affordable from those that are more hype and reputation.
