As Trivaldi suggested in other thread, I'm making separate thread for this idea.

Remote citycom would allow runners to access network everywhere they are. Since mails cant have attachments, making them accessable only from certain locations dont make sense, especially in cyberpunk game. Re-doing same mission would be faster if we dont have to run forward and back to citycom station. For example some HQs have not comfortable located citycom, resource manager and fsm for doing res/cst missions, it take more time running between them than actually doing item.
Implementing them shouldnt be hard - we can use existing hacktool model and icon. I propose HEW as vendor, since they have all hacknet items. Price should be around 30-50k nc. If it need downsides for use wrist computers than citycom stations, I propose adding ability for hacker to track location of player with citycomtool, or from time to time ability to disrupt system completely making it unsuable for hour or so.
