On September 4th 1998 The American & Irish Governments signed an electronic communiqué on e|commerce.
The signing at Gateway in Coolock was facilitated with technology by Baltimore Technologies. I was webmaster at Baltimore Technologies 1998-2001. The digital signatures used on the day are still available while the website of Baltimore.com is long gone. The project involved working with White House officials and Irish Government civil service getting the branding correct. The presidential seal is a highly protected brand. The branding was used in the website and the digital signing application and associated video and marketing material.
