I’m new to I2P, so this post will probably contain misunderstandings.

Since I2P takes on the order of hours after initial launch to build out a usable network of tunnels, does it make sense to use on a laptop which is regularly being put to sleep? Does suspension of the machine (disconnection from the network) completely cut off all tunnel progress, and it needs to restart the building from scratch when awoken?

Is the only practical way to use I2P from a laptop to have it running on a separate machine which is on all the time and remote connecting to it, like shown here?
