I don't really want to change the date and time format, but I guess a
configurable date and time field should be okay, so people can decide which
format to use. However, currently there are a lot of other issues with xlog,
that I want to program first. Unless you can come up with a patch,
there is not a big chance that your date and time wishes will be in
any of the next versions.

Right now, xlog does exactly that. Frequency is read from the rig, as the 
rig offers it. With my TS-870, I can read the operating frequency with 10 Hz
accuracy.

Version 0.7 will have free fields, which you can give any name. I will start
with 2 free fields, for the time being. Adding more fields will likely happen
in future versions.
Shared memory is intended for exchanging callsign data with twpsk. Xlog puts
data into shared mem, which is read by twpsk, so it's exactly the other way 
around.

The way to go would be through IPC message queues. It is explained in 
sendtoxlog.c
and the README.
