I for one, would love to have some of that stuff to wear to lanparties. Now, I'm not sure how far copyright would go here. If the shirt was created using MVP models, created by the users, and didn't say Freespace on it anywhere, and since the models are improved versions of the original freespace ones, would that be infringing?
On top of that, gear featuring just Hard Light Productions alone wouldn't be infringing on anything since that's their own copyright.
So how about it? Should we clamor for a return of the HLP store?
Also, if HLP had not for profit status (not sure if it does or not), profits from gear sales could go solely to running it and bandwidth costs, preventing it from looking like profiting off of Interplay's works. Just some ideas that ran through my head, probably just a pipe dream.
