I agree with you David. As a matter of fact, I was working on the php walkthrough of the databases to produce an sql export for an upcoming release. If you already have that done (or some part of it) we should collaborate.
The only issue is that the export has to be mysql import compatible. (or we can write a custom import script as well) The wonder of mysqldump is that the tables and all columns (and their features) are created automatically. However, considering the fact that a restore would be done after a vanilla install of wordpress, that is a non-issue.

@gamerz: passthru (and other system exec commands) will not work when php is running in safe mode. The command will only execute programs which are physically located in the folder specified by the safe_mode_exec_dir directive.
If your server is running in safe mode, you could try to make a folder in your web directory and put all the mysql binaries into it. Then add this line to your .htaccess:
php_value safe_mode_exec_dir “/folder/where/mysqldump/is/localted”
However, I checked with your server and it is not running in safe mode. So, if you are still with me, find this line in your backupRestore.php:
echo passthru(“mysqldump –opt -h$server -u$loginsql -p$passsql $base >$file_name”);
and replace it with this one. Let me know if it works and I will fix the hack to reflect all of the passthru functions.
system(“mysqldump –opt -h$server -u$loginsql -p$passsql $base >$file_name”, $retval);
echo $retval;

@gamerz: I am sorry, I should have said:
<?php
echo passthru(“whereis mysqldump”);
?>
Normally mysqldump is in the same search path as mysql. Try running the which mysqldump or whereis mysqldump.
