SQL, like Andre said. Or, if there's a reason to avoid it, a simple CGI 
script that will read the file and send lines as needed. Or (depending 
on the hosted server characteristics), a Rev based server using a 
different socket.

But you should be able to do simple text file - so read on ....

I'd do whole file transfers, rather than (implied) single lines at a time.
   put url "ftp://myaddress.com/data.txt" into tData
   put line 1 of tData into var1

I'd consider compressing the file (depending on what other uses it is 
being put to). Guessing each field at an average 20 bytes, you have 1000 
* 15 * 20 = 30kbytes - could compress to 10-20K depending on data, and 
so half the transfer time.

It's very worrying that you say the file is liable to corruption - ftp 
shouldn't do that :-).
Is it being accessed by multiple clients at same time ?
How are you doing the writes to the remote file ?
