XMLRPC.php broken by satellite connection latency

I’ve been using the XMLRPC.php file with ecto to publish my blog posts just fine, until I came to upstate NY. Where I’m at now there is a DirecWay satellite dish for broadband, and it seems to break the ability to post. This is true both for me – I’m using a nightly build from last week, and for my wife, who is using an older nightly build from a month or two ago. What happens is that it actually saves the post as a draft, but it doesn’t upload the categories or publish the post. Here is the error it gives:
Response:
{
“/FaultCode” = -65794;
“/FaultExtra” = {domain = 4; error = -1; msg = “Stream Error”; };
“/FaultString” = “/CFStreamFault”;
“/kWSResultIsFault” = 1;
}
I assume this is somehow related to the latency in satellite internet connections, but that is just a guess.
