So i did some research on this idea.

Very slanted, but has some interesting points
http://blog.dlink.com/why-using-a-wi-fi-portable-router-is-better-than-tethering/

and they suggest this device, which i think is pretty spiffy for a portable device to do this very thing.

And then you can use any DDWRT compatible router in this manner

Your best bet is probably to buy a normal home router and get yourself a generic usb cell data stick, most anything that will run dd-wrt will support using them as the "wan".  Most netgear, asus, buffalo, etc routers come stock with dd-wrt, or some bastard oem version thereof.  Just google the model you're thinking, and make sure they're supported by open-wrt or tomato case the oem version sucks.

You don't even need a new/modern one unless you want 802.11AC (so your mac friends with new powerbooks don't turn their nose at you), so hit Craigslist/ebay too.

Problem with a phone is they usually won't have enough power and antenna to deal with that many clients, whereas a router, especially one that has sma connectors for external antennas, will.  They also do nifty things like supporting 5ghz clients vs. just 2.4ghz crappiness, channel-bonding, channel-steering, etc.

Attaching 50 clients on even an enterprise ap is a lot for one channel...  Your phone will go insane, and interference from that many speakers will make it useless.

Simple question: I'm looking to see if anybody knows of any mobile apps that run in either iOS or Android that support a "mobile hotspot" (or "personal hotspot") and allow more than 5 DHCP connections? Preferably up to 255, although 50 is about as many as I'd need.

What I'm looking for is the ability to configure a mobile device to support a micro-LAN where people in a meeting room can communicate through a single sub-net without having to rely on the facility's WiFI router (because they frequently block most ports) or an external router (if a phone or tablet works, why require another device?).

I don’t even need to get to the internet. It’s just a way for mobile devices to communicate with a single “host” device where everybody is sitting at the same meeting.

Thanks!
