Updating software via web

Can you update the user managed code while the GHI chip is connected to the Internet?
This would be used for remote updating of the managed code. And would necessitate a hard reboot. We can remotely power down and power up the chip but can the code be sent to the chip remotely?

Depends on what GHI product you are using.

GHI ChipWorx

Yes all this is possible on ChipworkX. Check Pyxis 2 source code:
