Arquitecture --- Help!!

Hi guys, I need your opinions and suggestion

this is the scenario

40 or more clients distributed along the city (those are like Kiosks), each one is collecting information in a DB locally (MSAccess xx) , and each one has to update a central statistics DB (SqlServer7 or 2000) located in a Server Remotely every 5 or 10 minutes, using a wireless net to access the internet at 56kb (The package to send is going to be 4Kb max per trip), this in not an online-fulltime connection, the access to the net is only made when it is necessary to update the statistics server (via modem), also it is not VPN

Requirements
The App on the clients have to be as light as possible cause the machines are not powerful, those clients machines are only to collect data locally and then send it to the server

My solution so far

* Client App: VB6 - MSAccess Or VB.NET - MSAccess (It Depends on the hardware .Net requirement

* For communication: VB6 - Interop - Web Service - SQLserver Or VB.NET - WebService – SQLServer

* On the server: A Web Service(s) updating the Statistics D

My questions:

* What are the minimum Requirements (Mhz ,Ram ,SO) for a client machine running a .Net App
* Am I on the right way or am I totally wrong, How would you make it

Any Idea will be appreciate
Thanks,

Kenn
