Snake, not sure what you aim for.
Presumably you want to identify their commlinks nodes and identify parlor nodes.
There is at least several dozens of non-hidden nodes within 50 meters from the parlor.
Some of them are in public mode, broadcasting their exact positions, and facebook like information.
Filtering them out there is still 20 or so nodes without any special AR overlay. Since none of them gives you user credentials you can't pinpoint them if they are the bouncers' links. The basics of matrix security hints they should be hidden and encrypted, but they might have the security flaw up there.
To check all the available nodes you need to hack all non encrypted ones. This will take you 10 minutes to check them all (with the compelx forms you carry no rolls are necessary for that), less if you hit any of them earlier. to hack all the encrypted ones will take few hours at least, and that basing on assumption there is no matrix geek around that walks with his link encrypted with 24h interval..
Let me know if you check the public/weak encrypted nodes nodes.
If you try to scan for hidden nodes using other equipment, remember to apply -2 for additional try. and that it is a limited extended test
if you teamwork, Omar, can use the 1 hit you generated as bonus to his dicepool
