connect 'droid tablet thru 'droid phone to internet

[saintdanbert]

I have an Android phone and Android tablet. I don't need it often, and I don't need high bandwidth or throughput. Can someone tell me if there is a way to do this?

• the Android phone has access to the internet over 3G or 4G
• run some app on the phone
• run some app on the tablet
  
  • use Bluetooth or ad-hoc wireless
  • "network" TCP/IP between the two 'droids
• both the phone and the tablet can access the internet

I know there are full blown hot-spot and network sharing arrangements for sale. I'm looking for something simple, straight forward, and not much fuss.

Thanks in advance,
