While it is not a panacea, the still developing HamGate project could help. Go to http://hamgate.ampr.org and make sure to click the docs link. There are operating HamGates in ME, MA, RI, CT, NY, NJ & PA. There is movement for one in MD and possibly OH. This was all borne out of the frustration of 44net allocation holders with IPIP issues or those behind NAT situations.

I don't think this is possible with a hotspot from a cellular connection.
You are behind a nat on cellular, which shares one public IP with many and doesn't allow routable ports/protocols.
The only solution would be to get a public IP address from a home connection or a vps, and setup a VPN to access it from remote.
I could be wrong, but that is my understanding at this point.
Not only that, but some VPSs do not allow loading the IPIP module, which means that a full KVM virtualized private server is the only solution short of setting up a VPS to announce a /24 via BGP.
