SSRS extension which to use

Question

Hi Folks
I'm believe I'm needing to add an extension to SSRS.
I'm trying to shy away from anything related to a Security extension, basically because our security works pretty much as  it should with the current scheme.
I think a Data extension is the route that I need to go. Here are the details.
1. reports are reports, and what we have is just fine in terms of content, layout, etc. (and we are running  with a single customer currently).
2. we need to scale for potentially thousands of customers. each customer has their own
OrganizationID. From this OrganizationID, we need to
calculate the connection string and image library path.
3. we need to use our own form of "Global Directory" (WCF, etc.), passing an OrganizationID to this directory service in order to return the associated customer's datasource connection string and the associated image library path (this needs to
happen pre report render).
Is the SSRS Data Extension a good approach for this kind of scenario? Are there any known pitfalls, design considerations, etc. that I need to be aware of up front?
Thanks

To be more specific, I'd like the ReportParameters in the snippet below to only be 1 (publicOrgID instead) and the information for what's currently in-bound into the report
(param[0], param[1]) we want to have calculated on the server side.
                    SSRSGlobalDirectory globalDirectory = new SSRSGlobalDirectory();
                    string
publicOrgID = Utility.Util.GetPublicOrgID(Convert.ToInt32(Session[Resource.HC_StringConstants.HC_MYSTOREID].ToString()));
                    globalDirectory = SSRS.CallGlobalDirectoryforSSRS(publicOrgID);
                    ReportViewer1.ProcessingMode = ProcessingMode.Remote;
                    ReportViewer1.ServerReport.ReportServerUrl = new Uri(globalDirectory.SQLReportServiceURL);
                    ReportViewer1.ServerReport.ReportPath = Resource.HC_StringConstants.HC_FISUMMARYREPORT;
                    ReportViewer1.AsyncRendering = false;
                    ReportViewer1.SizeToReportContent = true;
                    ReportParameter[] param = new ReportParameter[2];
                    param[0] = new ReportParameter(Resource.HC_StringConstants.HC_SQLCONNSTRING, globalDirectory.ConnectionString);
                    param[1] = new ReportParameter(Resource.HC_StringConstants.HC_IMAGELIBRARYURL, globalDirectory.SiteImagesURL);
                    ReportViewer1.ServerReport.SetParameters(param);
                    ReportViewer1.ServerReport.Refresh();
