I am sure it is a priority for Square Connect, but they are very busy and dedicated to current developments.
iPad doesn't have iOS4 yet, so they have some time in my opinion to enable support.
Things on their list include:
"the puck" Wi-Fi to IR system hinted to on their website
SQ Remote version updates
iPad optimized version
iOS4 support
There is no order intended here or promises, just my observation based on their forum communication. They are poised to deliver as always, FYI.
