Opbservations worth considering
1) could possibly be handled by a simple bash script (My bash skills are
not great So i would probably still go python myself anyway)
2) Instead of checking availability just try to send & react appropriately
if it fails (Ask for forgiveness not permission), the client could fail
after test or during transfer anyway so you will still need this level of
error checking
