Ada Technogies suitable for the following

Hi,

Looking for Ada technologies suitable for a project involving 
communication between a client on someones pc and a server somewhere. 
The server is responsible for responding to requests which can either be 
XML files containing a catalogue of search results, or a media file.  It 
is also responsible for user account management, involving the crediting 
of user accounts.

The client allows the user to query the XML file for results, and 
approving downloads of media files.  The idea is to free up the server 
as much as possible.

The idea is that each user should buy a pay an amount of money up front 
and be allowed to download media up to the value of credit on their 
account.  They may update their credit at any time, allowing them to 
download more media.

What technologies could be used for this?  Obviously there is XML/Ada 
for the XML element, but what else?  AWS looks like a good bet for the 
communication between client and server, although I'm not sure of it's 
overall suitability (never done any network programming before and just 
downloaded it, so am ignorant of it's capabilities).

I was thinking of GtkAda for the gui component of the client, but am 
unsure of the status of the Windows port of GtkAda 2.0.  I will check 
this on the gtkada client list.

What are peoples thoughts?  Are there any Ada technologies you think 
might be useful?  This is really an exploration of the technologies 
available for such a project, there is no real commitment or even intent 
to do anything serious with the idea.  If sufficient technologies exist, 
I may reconsider, but I am very busy with other things.


Regards,
Chris Campbell
