Yes, and yes. My Common/UI library does exactly this to provide standard about dialogs, VFS open and save dialogs, help display, and more. The library even includes application icons for itself. You have to worry about mapping over someone else's resource IDs (ID collisions) - having two forms with the same ID is just asking for it.
Most of my Common/UI resources are either below 1000 or above 9000 (but below the system-reserved 10,000). The way this works is the system looks for requested resources (forms and whatnot) in the most-recently-opened-database first, then in other databases by order of opening. Thus it will look in the library, then the application, then the system.
There is no way to hide resources in your library from the active application that is using it, so be careful when assigning resource IDs!
Be careful with the above 9000 space. PilRC's default auto ID generation code starts at 9999 and counts down. With PilRC 2.9p10-CW and later, you can use "RESETAUTOID" to change the range of auto ID's generated by the tool. For small apps, this may not be an issue, but I'd probably stay away from 9500 and higher.
