Should all wireless USB keyboards work with the TVs network server. If not, is there a certain specification that would make a wireless keyboard compatible with our sets?

All USB keyboards are pretty much standard.   For USB wireless keyboards, it may be different since they may use different technologies (Bluetooth, 2.4GHz, IR, etc.,) for the wireless part. The main problem that may occur with a wireless keyboard is if the keyboard requires a special driver to make it work on a windows pc - if it does, then it is highly probable the driver is unique and our TV won't be able to communicate with it.   Customers should go with a well-known brand of keyboard (Microsoft, Logitech, Kensington, for example) that way the customer will at least have the option of reaching out to the manufacturer for support should he need it.
