Nice to meet you too Art. And thanks for offering to do (any)
presentation. At least among those present last night, I think there's
consensus that virtual glug meetings would benefit from a bit more
structure.

This sounds great to me Art, I imagine a lot of us have problem sets
like a mixed use home nas that has both "important documents" and a
media library.

Oh good instinct to seed future talks. I've no history with gopher
