Rather than using a Handler(.ashx), is it possible to use a web service(.asmx) to upload?
Any suggestions on how to use a jQuery upload to get the input stream?
VB.NET code or examples would be appreciated.

Yes it is possible , you can pass the File to the service(.asmx) , and get Json back by specifing the response type. better soultion if you want a simple uploader with drag and drop functionality would be Ajax uploader - valums
_uploader = new qq.FileUploader({
element: document.getElementById(_Uploaddiv),
onComplete: function (id, fileName, responseJSON) { },
action: '/Uploader.asmx/functionName',
params: {
startRowIndex:_startRowIndex,
pageSize:_pageSize
}
xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
xhr.setRequestHeader("Accept", "application/json, text/javascript, */*; q=0.01");
set the XMLHttpRequest() headers to Accept json
VB code
<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _
Simple , light, accepts my CSV and gets me the result. that's what i wanted

Jquery has a Forms plugin which can be used for this purpose. The good thing about it, it supports file upload using AJAX as well.You can locate it here http://plugins.jquery.com/project/form. We are using it with MVC 3.
