Todd,
Terrablock (AKA “SAN in a Can”) has gotten good reviews and is well accepted in the community. It shines in a small scale environment where you don’t have the $$$ or time/talent for a more complex system. Sounds like a good fit for you.
As for project sharing… there is no free lunch and it’s going to be more complicated with the limitations of your Terrablock “volume based” system. If you want true scalability and univerasal sharing, you’d want to be looking at X-SAN.
I really don’t understand all this “hooey” about “project sharing”. Anyone coming from an AVID environment trys to scare the pants off of you by saying “you can’t share projects”. With FCP, essentially, the SAN IS THE PROJECT. (At least with X-SAN). We’ve developed a workflow with many, many editors (almost 100) where we regularly copy and use each other’s projects. It’s not a problem. You just have to organize your media in a “global” way that everyone can understand. And, of course, using the filename to add comments (like many Avid users do) is also not a good idea. That’s what the “comments” column is for.
