Well--

I'd say coffee or something similar at a public and musical type venue (coffeehouse, say ;>) and talk about mutual musical interests. Based on how you feel, take it measure by measure at whatever tempo seems comfortable. I never liked the baseball imagery anyway. If you're both sensitive and open to collaboration and mutual assistance, you'll get to the double bar line at the same time.

Just my $0.02. Mileage may vary.
