I should be back on later tonight (starting 18:00 or 20:00, GMT -4), but that's probably way later than you want to do this. Other than that, I have an hour between 16:30 and 17:30 on Tuesday (20:30-21:30 on your end), and on Wednesday I've got windows between 8:00 and 10:00 (14:00 and 16:00 on your end), and between 16:00 and 18:00 (22:00 and 24:00 on your end). We may have to do this in spurts, but we'll get it done.
