yep! determine your computer's ip address by going to the command prompt and typing ipconfig ... you'll get an ip or ipv4 address... and then enter that address into the address bar of the other devices' browser. like magic.
here's something to blow your mind... all websites are exactly like that. just ip addresses. DNS resolves names like yahoo.com to numbers like 184.108.40.206. so you can type yahoo's ip address (they have many, just pick one) into your address bar and it'll take you there. now, you can't get to 192.168.1.x unless you're on your own home network... to access it from outside requires some massaging. but that's pretty simple too.
